Canon EOS M Review


The EOS M is Canon’s first foray into the mirrorless camera market that is currently dominated by Micro Four Thirds models from Olympus and Panasonic, along with Sony’s NEX lineup. The EOS M was welcomed with a collective “It’s about time…” from most of the digital imaging press, who have wondered when Canon would get around to participating in this exploding market segment.

First impressions on Canon’s unveiling of the EOS M were mixed – with some excited to see Canon utilized such a compact form factor while retaining the APS-C sensor – and others (primarily enthusiasts) wondering why there was such a neglect of their market segment by the failure of Canon to include features like a viewfinder.

I sat on the fence – seeing the potential of a mass market mirrorless camera that segued easily from the point and shoot “feel” and into the professional image quality yielded by the large APS-C image sensor. When I saw the image quality first hand at PhotoPlus 2012 on a pre-production model, I was impressed with what Canon managed to do with a camera so small.


Now that I have had the chance to use the EOS M extensively, I am nothing but frustrated with the camera. The EOS M had the potential to be THE breakout camera in the mirrorless market – except for one fatal flaw.


For all that it is with beautiful image files produced from the excellent 18MP APS-C CMOS sensor inside of it, the ridiculously slow autofocus completely ruined the camera for me. And, it’s a camera that I wanted to like so very much.

Using the Canon EOS M with its 22mm f/2 kit lens, I can’t count the number of times that I held it up with a subject on the LCD, half-pressed the shutter button to activate the AF and waited . . . and waited. Frequently, I had time to talk to camera (in angry phrases that I won’t repeat here) while it attempted to focus.

The worst, however, was attempting to video with the EOS M as it tried to hold autofocus. It would pump in and out of focus for what seemed just for the heck of it. I cannot understand why a camera manufacturer that makes excellent video cameras throughout pro and consumer lines cannot get the AF right for the video function of its DSLR and mirrorless cameras.

Everything else on the camera is quite wonderful in my book. I know some folks wanted to see a viewfinder on this camera, but I was going to be ok without it. The controls and ergonomics were overall good enough for where I thought the camera fit in the market – positioned against Sony’s NEX-5R and its ilk from Olympus and Panasonic. I could have used a little more “grip” for my right hand, but other than that, the camera was just right.


Unfortunately, I cannot recommend the Canon EOS M to anyone. Sure it takes existing EOS lenses if you purchase the adapter, but if you have been holding out for an EOS mirrorless camera, my recommendation is to keep waiting.

If you’re not tied to the Canon brand, go buy the latest and greatest from Sony, Olympus or Panasonic. Image quality may be marginally lower than the Canon EOS M; however, usability will be much higher up the ladder with almost any of the current models from Sony, Olympus or Panasonic.

My personal recommendation for an entry-level mirrorless camera would be the Sony NEX-F3, which will soon be replaced by the Sony NEX-3N. Sony’s NEX “3 Series” keeps getting better and better and, unless Canon really nails the next EOS M-series camera, it remains the entry-level camera to beat in my book.

    I had a similar experience to Eric – I bought this for my wife and am deeply disappointed in it because of the auto-focus. Took it to a party and had large groups of people staring at me and smiling while the camera completely failed to focus – very embarrassing. It’s great for still subjects in plenty of light, but I can’t predict before going on a trip whether I will always be photographing under those conditions. The first Canon product that I feel I wasted my money on, and I am making sure I dissuade any of my friends who are considering such a purchase.

    I fully agree and also frustrated with the camera’s AF from what I have seen so far…

    I thought canon coming last would get things right off the bat but NO…stupidly launched the camera to test the water.

    Even though last in the race to have a camera that meets most amateur to pro’s requirements as a prime or 2nd camera body that could ultimately use high quality lens to meet the sensor resolution. ..But no the group that designed it completely faltered. At close to $1K, what was canon thinking that uses are stupid? this camera feels like what I had 6 years back where you point and 2min later the camera is all set to take shot but the scene is all changed

    I hope canon learns that there reputation is on the line and put out worth wile products that meets the consumer expectation and compete in the market.

    Can the photo shoots are about timing and capturing the moment as per your own advertisements and not minutes later.

    It’s a pity that this camera has this so weak AF.

    Canon said that sales of EOS-M are not as expected due to lack of more lenses, but we all know that it’s because there are some missing features and weak AF.

    We’d like to note that EOS-M had a feature at the moment of announcement that was removed after, and even some customers bought this camera thinking the feature was there. Another disappointment:

    Another concerning issue we noticed is the amount of hot pixels in stills. I personally can’t check if there’s a way to get rid of them, or remap the sensor. Anybody can let us know?

    We all wanted to love this camera, indeed. The next EOS-M will probably be released soon at higher price. We hope the price will be not so higher, especially considering there are lot of other mirrorless cameras with more and better features like Peaking, 60 fps at Full HD, etc…

      Agreed. If the AF wouldn’t have been an issue, these things would have been flying off the shelves. I would have bought one for a personal kit. The image quality is just so darn good on this thing. Too bad…

    The EOS-M is a dud. It’s over priced, under functioned and nearly useless in many situations.
    The G series is a better answer for someone who has to have a Canon label, but almost any
    M43 camera will out perform it. The expensive lens adapter is also a joke. In any case, a
    Canon T3 at $450 (with the 18-55 lens) is a better experience and with the 40mm pancacke lens it isn’t that much bigger than the M. A Canon exec recently said “M sales didn’t quite
    reach expectations” – I say it probably never will without major improvements.
